Otisec is here to help us prevent this and allow us to enjoy a more comfortable experience when we get out of the water. Otisec is a spray specially designed to remove moisture from the ear, protect the physiological pH of the ear and prevent otitis externa. Otisec is a health solution used by professional water athletes, but it also provides the general public with a more comfortable experience after swimming, allowing their ears to be free of water without having to shake their heads.
